SOURCE: Problems with Gearshift 2004 Lincoln Navigator

Turn the key forward a notch then it should come out. If you are turning the key all the way off it enables the accessories (radio etc), locks the key in the ignition and disables the gear shifter.
If thats not the case then there is a button to be depressed so that the key can turn anticlockwise>off another click and the key can be removed.
It'll be one or the other....faulty ignition lock is the only other diagnosis

If the air conditioner compressor is seizing it could cause the vibration you experience.

SOURCE: 2005 lincoln navigator check enigine

Hello, Check your engine oil first. Then I would say to drive to an Autozone or Oreillys for a free scan to get the Code from the onboard computer. Since your engine has a knock you should not drive it. Call the Dealer for a Tow.

But there is some good news if you meet the mileage requirements of an Extended Warranty for owners with 4.6L and 5.4L engines built between 2004- 2008. Call with your Vin# and tell the Lincoln Dealer you think you have a Cam Phaser problem. This problem has a Warranty extension of 7 Years and extra miles.

The problem is a part which keeps the valves synchronized on both sides of the engine. The Cam Phasers are expensive and labor intensive to replace. If you do not get help from Lincoln, there are cheater tools on the market to cut Labor by half. But a Novice should not attempt this repair.

You should get the Codes read by a scanner. You can also have a different problem with the sparkplugs backing out. The Knock you hear could be escaping compression from the cylinder head. The scanner will identify a problem cylinder.

I hope my Solution is helpful. There is really no good way to tell you it is not a do it yourself fix without you having experience and a good range of tools.

Over heating in 2004 lincoln navigator


Are you losing any coolant ? Any leaks , heavy steam out of the exhaust ? Fluid level in radiator or overflow reservoir good ? Can you see the fan/fans running ? If fan/fans not running turn AC on and see if they run then. Could be thermostat not opening completely or water pump going bad. Radiator may be clogging slowing circulation.

My 2004 lincoln navigator making knocking sound when I start up and drive a certain speed


Have someone check it for "cam phasers" which were a problem in 2004-2008 V-8 engines. In non technical terms there were 2 identical parts to set engine timing automatically. If either works a little differently you will have the problems you describe.

I put in mobil 1 10w 40 oil in a 2004 lincoln avaitor and its still knocking...what oil should I use now?


If it is knocking you have bigger issues!

There are several "knocking" noises an engine can make. Most of them are not good. A good tech with a trained ear will be able to help narrow down the possibilities.

Some possibilities are a spun bearing or a rod knock. If it is either of these it is terminal and no oil will help. An engine rebuild or engine swap will be the only fix.

Clicking noise coming from the back of our 2004 Lincoln Navigator when we are driving. What could this be?


Clicking could be from any part of your suspensions. Have a mechanic look at it as a manual diagnosis of the car in person will be necessary

When I get up to about 65-70 mph with my 2004 Lincoln Navigator it makes a humming noise... very annoying.. Can anyone help me with what this is and how I can get it fixed?


Unfortunately, this is a somewhat common problem. Ford has issued several Technical Service Bulletins related to rear end noise. Without an extended warranty, this is something you will have to pay for.
TSB 05-23-3 11/28/05 REAR AXLE NOISE REPAIR FORD: 1997-2005 Expedition, F-150 2002-2005 Explorer LINCOLN: 1998-2005 Navigator 2003-2005 Aviator MERCURY: 2002-2005 Mountaineer
ISSUE:
Some vehicles may exhibit an axle whine or hum during acceleration, deceleration and/or cruise.
ACTION: An axle repair kit has been developed which incorporates most parts required for a comprehensive axle repair. The kit should be used instead of installing a complete axle assembly to repair an axle whine/hum. Replace Ring and Pinion with Axle Kit and Components.

Knocking noise


Not good to have a knocking noise.
An engine knock can be serious signs of engine failure coming soon....whatever it is have it looked at right away before you have a complete break down on your hands.

This is caused by a blend door actuator on the rear a/c unit. There are 2 located on the case. Take it to a dealer and they will know what you are talking about.

I have a 2004 Lincoln Navigator with 35,000 miles. Lately I get a loud noise at higher RPMs like going up hill at around 60 MPH. Sounds like I am dragging a huge piece of tinfoil under the front end of the...


It could be spark knock. You should have a sensor to keep that from happening. So will a tank of Premium gas.

Another possibility is a loose heat shield on the exhaust system. Lincolns usually have longer warranties, call a dealer and see if it is covered. If it is part of the emissions system, the warranty is even longer.
